The Optibelt 50 AT5K6 / 3400 AFX is an AT5 profile timing belt with a 3400 mm length and a 5 mm pitch. Before you fit this belt, inspect the drive and sheaves so the new belt runs on a sound system. We carry this Optibelt belt and quote by part number.

Start with the sheaves. Check for worn grooves, burrs, corrosion or debris that can damage a new timing belt. Confirm the sheave teeth match the AT5 profile and that the 5 mm pitch is correct for the pulleys. Misaligned or damaged sheaves will shorten belt life, so correct them before installation.

Next, check the drive for alignment, bearing play and any signs of rubbing or oil contamination. A timing belt with a 3400 mm length can be difficult to fit if the drive is not in good condition. Verify that the tensioner, if present, moves freely and that all fasteners are secure.

When you are ready to order, send the part number 50 AT5K6 / 3400 AFX by WhatsApp or email. Our team replies promptly and can help confirm the right belt for your drive. If you need to match an existing belt, include the marking on the back so we can cross-check the profile and length.
